Subject: [mg28774] [mg28766] Converting {{a,b},{c,d}} to just {a,b},{c,d} (no
enclosing parens) ?
How can I convert a list of pairs, like
{{a,b},{c,d},{e,f},. . . }}
into just a sequence of pairs, i.e.
{a,b}, {c,d}, {e,f}, . . .
with no outer { }'s?
Reason for doing this? Want to define a Line in the form
Line[{pt1, pt2, pt3, pt4, pt5, pt6, . . . . . . }]
where some of the points, say pt1 through pt4 are individually defined;
but then a sequence, say pt5 through pt20, are defined by a Table; then
pt21, etc are back to individual definitions.
I know -- I could break these into a sequence of Lines -- but it would
be cleaner if there were a simple way to have one Line[ ] command with
all the points inside it.
